Couldn't that be:
        
        result_found || tds->current_results == NULL

just as well?  That should be legal C everywhere.  

You don't need a memory leak for this to happen.  If you free the memory,
and don't set the pointer to NULL, the assertion will fail.  Maybe if we
used TDS_ZERO_FREE more consistently, that wouldn't happen.  (Not that I
do, but still.)
